Abstract
Ten male volunteers were utilized in a study of the perception of vibration. Four subjective reaction levels: perceptible, mildly annoying, extremely annoying, and alarming were established. The Boeing Human Vibration facility, modified since previous tests, was used as the test instrument. Experimental controls and test methods were determined in a preliminary study. Subjective levels identified are generally at higher acceleration values than those of previous research. Possible reasons for the differences are discussed. Also, individual values established at a given subjective level are shown to be influenced by the magnitude of the immediately preceeding vibration level. Physiological effects in the main correlate with previous findings.Keywords
